Description
Our Caramelized Onion Burger (or sliders) are the perfect Game Day party food that everyone will love!
Ingredients
Scale
Balsamic Mayo:
- 2 tablespoons mayo
- 1 teaspoon balsamic vinegar
Caramelized Onions:
- 3–4 sweet yellow onions, sliced
- 1 tablespoon extra virgin olive oil
- 1/2 teaspoon kosher salt
- 1/2 teaspoon ground black pepper
Burger:
- 2 pounds ground beef
- 2 teaspoons kosher salt
- 2 teaspoons ground black pepper
- ghee or butter
Serving Suggestion: hamburger buns or iceberg lettuce (for lettuce buns)
Topping Options: sliced cheese, bacon, and pickles
Instructions
- Balsamic Mayo: Place ingredients in a small bowl and mix to combine. Make additional sauce as-needed.
- Caramelized Onions: Bring a large cast iron skillet to medium-high heat. Add olive oil and move it around so that the bottom of the pan is coated. Add onions and sprinkle with salt and pepper. Move onions around in the pan and bring heat down to medium heat once onions start to cook down. Continue cooking onions 15-30 minutes, until they start to turn golden brown. Once onions are golden brown, turn off heat, and set aside until burgers are ready.
- Prep Burgers: Place ground beef, salt and pepper in a medium bowl and mix with hands to combine. Divide into 12 equal slider patties. Ensure they are approximately 1/2 inch thick. Make a small indent in the middle of each burger and place a small bit of ghee inside. Sprinkle the tops of the burgers with a little more salt and pepper.
- Cook Burgers: Turn oven broiler to HIGH and line a baking sheet with aluminum foil and place an oven-safe wire rack on top. Spray the rack with olive oil or other non-stick cooking spray. Place the sliders in a single layer on the wire rack and place in the oven on the middle rack to cook for 10 minutes (this will result in a medium-rare center). Remove and let rest at least 5 minutes at room temperature.
- Assemble Burgers: For a Paleo/Whole30 – serve with a caramelized onions, lettuce bun, bacon, pickle and balsamic mayo. For a non-Paleo/Whole30 option serve on a slider bun of your choosing, add some cheese and then the caramelized onions, bacon, pickle, and balsamic mayo.
Notes
- Whole30/Paleo: double check your ingredients on your balsamic vinegar, mayo, bacon and pickles.
- Full Size Burgers: Simply make 8 burger patties instead of 12. Make sure you are flattening them enough before cooking. Cook for 10-12 minutes for medium rare.
- Grill: another great way to cook the burgers/sliders, if you prefer!
